motion: Add decoding for MOTION_CMD_DUMP v1 command
MOTIONSENSE_CMD_DUMP is deprecated, replaced with MOTIONSENSE_CMD_GET_DATA
Also use vector_3_t instead of x,y,z
ectool motionsense commands only work with newer firmware, to
handle a dynamic number of sensors.
- The host sends the number of sensor it has allocated space for.
- If 0, the EC just sends the number of sensors available
- Otherwise returns sensor information up to the limit imposed by the host.
Remove MOTIONSENSE_GET_STATUS: not needed. It is only useful for LPC,
to guarantee atomicity of the data.
Remove MOTIONSENSE_GET_DATA: not needed since we increase the version
number of MOTIONSENSE command.
BUG=chrome-os-partner:31071,chromium:430792
BRANCH=ToT
TEST=Compile. On a firmware that support the new command:
/usr/sbin/ectool --name=cros_sh motionsense
Motion sensing active
Sensor 0: 92 15 1030
Sensor 1: -94 -63 718
/usr/sbin/ectool --name=cros_sh motionsense active
0
On a machine with older firmware (samus), check these
functions are not working anymore.
